faPINNING-BING HOLDER,

specification of Letters Patent.

Patented June 2, 191 1.

Application filed March. 8, 1909. Serial No. $81,8Y3.

To all whom it may concern Be it known that l, Gnonon L. France, a citizen of the United States, residing at Manchester, county of Hillsboro, and State of New Hampshire, have invented an lmprovement in Spinning-Ring Holders, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention relates to a splnnlng rlng holder of that type which is removably secured to the ring rail without the use of screws.

My present invention consists in provid ing the ring rail with a. plurality of inwardly-directed fingers which are adapted to overlie the upper surface of the ring holder, and in providing the ring holder with notches in its periphery which are adapted to receive the fingers whereby after the ring holder is properly positioned 011 the rail plate a turning movement of the ring holder will carry portions thereof adjacent the notches underneath the fingers.

I will first describe one embodiment of my invention and then point out the novel features thereof in the appended claims.

Figure 1 is a plan view of a spinning ring embodying my invention showing the ring holder secured to the rail plates; Fig. 2 is a plan view of the rail plate; Fig. 3 is a plan view of the spinning ring and its holder removed from the rail plate; Fig. 4: is an enlarged sectional view on the line mw, Fig. 1; Fig. 5 is a section on the line g y, Fig. 1.

3 designates the ring rail, 4 the rail plate, 5 the ring holder, 6 the spinning ring, and 7 the traveler. The spinning ring and traveler may have any suitable or usual con struction, and said spinning ring is shown as secured to the ring holder 5 in usual manner by means of the lips 8. The rail plate may be secured to the ring rail 3 in any suitable way, and I have herein shown said rail plate as provided with the tubular neck 9 which passes down through the ring rail and is secured thereto by a screw or other connection 10. The parts as thus far described may have any suitable or usual construction and form no part of my invention.

My improved rail plate is provided with the inwardlydirected fingers 11 which are shaped to embrace the edge of the ring holder. Tlhese fingers may have different shapes and can conveniently be made by making the flange of the ring rail with radially-extending arms which are bent over or doubled on themselves to form the fingers. Said fingers preferably have a por tion extending parallel with the flange a and situated therefrom a sufficient distance to provide a space to receive the edge of the ringholder. The ring holder 5 is made with a plurality of notches 13, each of a size to receive one of the fingers 11, said ring holder being made at one side of each notch with an abrupt stop shoulder 14, and being formed at the other side of the notch to present a portion 15 having its periphery at a radial distance from the center of the ring holder equal to or slightly less than the radial distance of the vertical portion 16 of the fingers. Each portion 15 of the ring holder terminates in a stop shoulder 17. In applying the ring holder to the rail plate, said holder is positioned above the rail plate so that the notches 13 come directly above the fingers l1, and when in this position the ring holder may be dropped onto the rail plate, the fingers 11 passing through the notches 13, as will be obvious. If the ring holder is now turned the portions 15 thereof will pass under the fingers 11, as shown in Figs. 1, a and 5, and the ring holder will thus be securely held to the rail plate. The stop shoulders 17 limit the turning movement necessary to connect the ring holder to the rail plate.

The fingers 11 are preferably resilient and are so arranged that they will have suflicient frictional engagement with the upper surface of the ring holder to firmly retain said ring holder in place.

If it is desired to remove the ring holder from the rail plate said ring holder is turned in the opposite direction until the shoulders let engage the fingers when said ring holder can be lifted vertically from the rail plate.

I have herein shown in dotted lines a suitable tool or implement for turning the ring holder to lock it to or unlock it from the rail plate. This tool is shown as provided with a handle 20 formed at its end with two arms 21 that terminate in downwardly-directed portions 22 the extremities of which are adapted to enter apertures 23 formed in the ring holder. The two arms 21 are so shaped that they do not interfere with the spindle which will be situated within the spinning ring.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a spinning ring, the combination with a ring rail, of a rail plate rigidly secured thereto and having a fiat upper face and integral inwardly-directed resilient holding fingers at its edge which are situ ated above said face, and a ring holder adapted to rest on said rail plate with its edge confined beneath and in frictional engagement wit-h the fingers, said ring holder having a plurality of similar notches in its outer edge spaced to correspond to the position of the fingers and of a depth to permit the ring holder to be removed in an axial direction when it is turned concentrically to bring the notches in alinement with the fingers.

2. In a spinning ring, the combination with a rail plate having holding fingers integral therewith at its periphery, each provided with a vertical portion and an inwardly-directed portion at the upper end of the vertical portion, of a ring holder having similar notches in its outer edge through which the fingers may pass when the holder is applied to the rail plate in an axial direc tion, said holder having portions adjacent said notches with the perimeter at a radial distance from the center less than that of the vertical portions of the fingers and also less than that of the outer edge of said holder whereby turning movement of the holder about its axis carries said portions underneath the fingers.

3. In a spinning ring, the combination with a rail plate having holding fingers, each provided with a vertical portion and an inwardly-directed portion, of a ring holder having similar notches in its outer edge to receive the fingers when the holder is applied to the rail plate inan axial direction and having a portion adjacent each notch, the perimeter of which portion is at a radial distance from the center of the ring less than that of the vertical portions of the fingers whereby turning movement of the holder about its axis carries said portions underneath the fingers, said portions terminating in stop shoulders to engage the fingers and limit the turning movement of the ring holder.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

GEORGE L. PIERCE.
